SpringMVC依賴

本文爲SpringMVC的依賴相關配置

1.新建一個Maven類的Web項目

2.將依賴添加到項目中/配置pom.xml文件

	</build>
</project>

3.在 web.xml 中配置 spring 配置文件的加載

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
	<display-name>Archetype Created Web Application</display-name>

	<!--解決中文亂碼問題 -->
	<filter>
		<filter-name>CharacterEncodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>utf-8</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>CharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<!-- 讓web項目自動加載spring配置文件 -->
	<servlet>
		<servlet-name>springmvc</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>

			<!-- 讓web項目加載springmvc的配置文件 -->
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>springmvc</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>
	
</web-app>

4. 寫 spring 的配置文件/springmvc.xml
（1） 配置 掃描 控制器的註解
（2） 配置 自動加載 SpringMVC 的註解掃描

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">
        
<!-- spring配置文件中添加組件掃描 
		掃描這個包下的所有類-->
<context:component-scan base-package="com.yc.controller"></context:component-scan>

<!-- scpringmvc註解驅動 -->
<mvc:annotation-driven/>

	
</beans>

5. 寫控制器 這裏是寫的 UserController

package com.yc.controller;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import com.yc.model.User;
import com.yc.service.UserService;

@Controller
@RequestMapping("/user/")// 根路徑

//	獲取不同detail其中{a}爲參數值可變
//	@RequestMapping(value="/detail/{a}/{b}")//多個參數寫法
	@RequestMapping(value="/detail/{a}")
	public String detail(
			@PathVariable(value="a") int id
//			,@PathVariable(value="b") int b
			){
		System.out.println("id:"+id);
		return "/user/index.jsp";
	}
	
	// 獲取頁面name屬性值
	//required=false表示值爲非必須，默認爲true(必須)
	@RequestMapping("edit")
	public String edit(
			@RequestParam(value="id",required=false) String id,
			@RequestParam(value="name",required=false) String name,
			@RequestParam(value="addr",required=false) String address,
			HttpServletRequest request,
			HttpServletResponse response
			) {
		request.setAttribute("id", id);
		request.setAttribute("name", name);
		request.setAttribute("address", address);
		System.out.println(id+name+address);
		
		return "/show.html";
	}
	

	@RequestMapping("index")// 根路徑
	public String index(){
		System.out.println("index.jsp");
		return "/index.jsp";
	}
	
	@RequestMapping("show")
	public String show(){
		System.out.println("show.html");
		return "/show.html";
	}
}

6.index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
